Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed May 13, 1905. Serial No. 260271- To (all whom it Herr/y concern:

Be it known that I, J'osnrn L. Hncn'r, of Davenport, county of Scott, and State of lowa, have invented a new and useful Improvement in Oil-Cups, of which the following is a specilication.

This invention relates to lubricators in the form of an oil-cup containing an oil chamber or reservoir communicating with the parts to be lubricated and having a closing lid or cap for permitting access to the chamber for lilling the same with the oil.

The invention is directed particularly to the form and construction of the lid; and it consists in providing the lid with a stop device of improved form arranged when the lid is opened to contact with the cup and limit the opening movement.

My improved stop device is employed in con nection with a lid which isacted on by a spring so arranged and connected that when the lid is opened the spring will be stretched and on the lid being released the spring will act automat' ically to return the lid to closed position. By the provision of the stop device the stretching action of the spring will be limited, so that there will be noliability of breakage by undue stretching.

The invention consists also in the details of construction and combination of parts hereinafter described and claimed.

l n the accompanying drawings, Figure 1 is a perspective View of my improved oil cup. Fig. 2 is a longitliidinal sectional elevation on the linea a of Fig. 4 with the lid in closed position. Fig. 3 is a similar view showing the lid opened and the stop in position to prevent further movement. Fig. 4: is a side elevation partly broken away to expose the internal construction.

1 represents an oil cup or reservoir, in the present instance of cylindrical form, with an oil-chamber therein, open at its top and bottom and provided at its bottom with a threaded neck 2,'by which the cup may be conveniently attached to the bearing or other part to be lubricated.

Near its upper end the cup is provided with twolaterally-projecting vertical ears 3, with a space between them, in which space extends a tongue at, projecting downwardly from the edge of a lid or cap 5, adapted to close the upper end of the cup, the parts being pivotally connected together by a transverse pivot-pin 6, ex-

tending through the ears and the tongue be tween them, the arrangement being such that the lid may be swung upward on its pivot, as shown in Fig. 3, to open the upper end of the cup.

Situated within the oil-chamber and extending longitudinally is a spiral spring 7, having its upper end connected with the lid on its un-- der side and its lower end connected with a transverse pin 8, lixcd to the walls of the oilchamber near its base. This spring when the lid is closed, as shown in Fig. 2, is under tension and exerts a pull on the lid and holds it yieldingly in closed position against the top of the cup, thus effectually sealing the same. The lifting ol. the lid to open position stretches the spring and places it under greater tension, as shown in Fig. 3, so that when the lid is released the spring in tending to resume its normal condition will quickly and automatically pull the lid down to closed position.

In the absence of any means for limiting the opening movement of the lid there is danger of the spring being stretched unduly and risk of breakage by turning the lid farther back than is necessary to permit access to the cup. To avoid liability of this action, 1 provide the lid with a stop which when the former is opened will engage the cup and prevent further movement. i prefer to form the stop on the tongue 41, the extremity of which is provided with a flat stop-surface 10, which when the lid is closed extends at an inclination from the outer side of the cup outot' contact with the same, but which when the lid is lifted approaches the cup and engages flatly against the same, and thus etiectually arrests further movement.

The relation of the stop, the pivotal connection of the lid, and the side of the cup is such, of course, that the lid will be permitted an opening movement suflicient to allow the cup to be tilled with oil, but not suflicient to unduly stretch the spring, so that the latter while being enabled to properly perform its functions in effecting the automatic closure of the lid is protected from injury and all risk of breakage prevented.

Having thus described my invention, what I claim is- 1. In combination with an oil-cup formed. with an oil-chamber open at its end and admit ed to communicate with the parts to be lubrieated, a lid hinged to said cup and adapted.

to close its open end, an extensible spring situated in the oil-chamber and connected respectively with the cup and lid and tending to hold the lid yieldingly closed; whereby said spring will be stretched when the lid is opened, and a downwardly-extending stop-lug on the lid, said lug adapted when the lid is raised to approach and contact with the side of the cup, thereby limiting its opening movement and the consequent stretch of the spring.

2. In combination with an oil-cup formed with an oil-chamber open at its end and adapted to communicate with the parts to be in bricated, a lid hinged to the cup and adapted to close its open end, an extensible spring connected respectively with the lid and cup, and acting to hold the lid yieldingly in closed position; whereby said spring will be stretched when the lid is opened, and a stop-lug on the lid extending downwardly therefrom alongside the side of the cup when the lid is in closed position, and iiormed on its end with a fiat stop-surface extending at an inclination 3. In combination with the cup, vertical ears projecting from the side of the same, a lid for the cup, a tongue on the lid extending downward between the cars, a pivot-pin extending through the ears and tongue, the said tongue being formed with a stop-surface adapted when the lid is opened to contact with the side of the cup and limit its movement, and a closing-spring acting on the lid.

In testimony whereof I hereunto set my hand, this 29th day of April, 1905, in the presence of two attesting witnesses.
